# From Bryan Liles on the Practicing Ruby Discussion List

1. TDD is a great tool. As a tool, you'll use it when appropriate.
TATFT mostly means that you should be thinking about how you can put
whatever you are creating under test at all times. Writing tests for
the sake of writing tests is silly.

2. Like Gregory stated, brittle tests aren't helping anyone. Think
about the ingress/egress points of your objects at all times.
